After the fire marshal halted ticket sales and turned away hundreds at Tampa Bay Comic Con on Sunday, it became clear the ever-growing event needed a bigger venue. On Tuesday, organizer Action 3 Events and Promotions announced it had secured approval to move the fan festival to the much larger Tampa Convention Center in downtown Tampa when it returns Aug. 24-25. Entering its fourth year as the convention's owner, Action 3 managing partner Stephen Solomon said Saturday's attendance of about 2,500, "by itself was a record-breaking number for us." On Sunday, even more people lined up — an estimated 4,000 — to shop comics and art and meet Lauren Cohan of The Walking Dead. Moving to the 25,000-square-foot convention center will more than double the space the comic convention occupied at the DoubleTree by Hilton Hotel in Tampa. Solomon said they will "do doubt" again be able to bring in sci-fi actors, celebrities and artists to the bigger venue and may add a preview night on Friday like other conventions do. — Sharon Kennedy Wynne
